Some cheese just isn't easy to handle with a knife—particularly if it's really soft or crumbly. Food weblog The Kitchn recommends a different tool for these cheeses: standard dental floss.

If you're spreading or mixing the cheese, this obviously isn't necessary, but if you need it cut into nice slices, dental floss is the way to go:

If the cheese is small, you can hold it in one hand while your other pulls the floss taught and does the cutting. For larger situations, place cheese on a surface, shimmy the floss beneath it, and simply slice up, holding both ends of the floss and crossing the two ends to complete the cut. Then repeat in equal intervals.
